DOORCHECK.

Application filed March 14, 1927. v Serial No. 175,177;

This invention aims to provide novel means With the above and other objects in view which will appear. as the description proce'eds, the invention resides in the combina-.

tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein'disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figurel shows in plan, a device constructed in accordance with the invention; Flgure 2.

is an elevation; Figure 3 is an elevation looking toward the bracket; Figure 4 is a plan, showing a modification; and Figure 5 is a section on the line 55 of Figure 4.

The numeral 1 marks a door frame to which a door 2 is hinged at 3, a bracket 4 being se-V cured to the door frame 1, the bracket-comprising a base 5 and arms 6 and 7 projecting from the base approximately at right angles thereto, the base 5 having a socket8 provided with a slot 9 in which moves a screw 10 having a ball 11 which rocks in the socket 8. The

16 is attached by securing elements 17 to the arm 7 and is located about parallel to the base .5, the spring tongue 16 having an inclined end 18. The spring tongue or brake 16 bears on the wide portion -12of the screw 10 and'is screw 10 is carried by the end 18 of the spring tongue 16, under the spring tongue, the spring member 24 swings on the bracket 23.

tongue bearing on the wide portion 12 of the, screw 10 and limiting, adj usjtably, the rotation of the screw 10, the screw 10 being rotated because the nut 20 is threaded on the screw. The construction of the device is such that it'will check the closing movement of a door efficient- A, I

ly and adjustably.

In the form shown in Figures4 and 5, parts hereinbefore described have been designated 5y numerals previously used with the suf- X a I j A bracket 23 is secured to the door frame 1*,

and to the bracket 23, a' holder 24 is pivoted as at 25, the holder 24 being provided with a recess 26 whichreceives the inner end of al screw 10 including'the ball 11*. T'he'holder 24 carries a bearing 27 which is received in'the I groove 15 of the screw 10*, the screw thus be-.

ing held on the holder 24for rotation. A I

spring brake 28 is', provided and bearson the 7 spring brake 29 is engaged by a screw 30 threaded into the holder 24. A look nut 31 on the screw 30 cooperates with the holder 24 to widened portion 12*, of the screw 10*, the

maintain the screw 30 in adjusted position,

brake 28 bears on the part 12" of the screw.

In the form shown in Figure 2, the screw 10 swings in the bracket 4, whereas, in Figure 4,

the screw 1O rotates in the member 24, and the What is, claimed is 1. In a door check, a bracket, means for I mountingthe bracket on a door frame, a

screw, means for mounting the screw for rotation and formswinging movement on the bracket, a nut into which the'screw is threaded, means for mounting the nut pivotally on a hinged door, a brake strip cooperating with the screw and extended across the screw in a direction approximately at right angles to 1 the length of the screw, means for securing one endof the brake strip, and mechanism ens gaging the brake strip, in spaced relation to the last specified means, for adjusting the braking effect of the strip on the screw.

2. In a door check, a bracket, means for mounting the bracket, -serew, means for mounting the screw for rotation and for swinging movement on the bracket a nut into p {which the screw is threaded, means for mounting the nut pivotally, a brake strip extended across the screw and means for securing the brake strip at one end, the brake strip being of such length that the-screw can swing en- In testlmony that I olaimthe' foregoing as my own, I have hereto aflixed my-signature.
